O-Ring

Engineered as a durable aftermarket solution for drilling equipment, the O-Ring (OEM 0663 6143 00) is an aftermarket replacement for Atlas Copco rock drilling and related equipment. It helps contain hydraulic oil, air or flushing media while keeping dirt and abrasive contamination away from critical interfaces. Listed compatibility includes BOLTEC 235, BOLTEC 235H and BOLTEC LC.

During drilling operation, it must tolerate repeated pressure cycles, reciprocating or rotary movement, temperature changes and contamination typical of drilling service. With application-matched sealing materials and accurately controlled profiles, the component is intended to install accurately and work predictably with adjoining parts. This supports stable sealing performance, cleaner operation and longer service intervals for the surrounding assembly.

Delkom supplies this item as a cost-conscious alternative for maintaining Atlas Copco drilling machinery without compromising the focus on fit and service reliability. Reference 120 100 061 for availability and quotation requests.
